Today i had a problem with my CD Rom, When i check the Status in Device Manager it says
Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)
So I was thinking why my cdrom failed! recently i installed some cd/dvd burning & copying softwares, so i understood that this is caused by those applications.
So here is how i fixed it, First remove all CD/DVD Copy/Burning Applications, and follow these steps
Step 1: Start Registry Editor
Click Start, click Run, type regedit, and then click OK. Registry Editor starts.
Step 2: Delete the UpperFilters registry entry
| 1. | In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE. |
| 2. | Expand SYSTEM, and then expand CurrentControlSet. |
| 3. | Expand Control, and then expand Class. |
| 4. | Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}. |
